Southwest was the last of the largest U.S. airlines to reach a deal with its pilots' union.

Southwest Airlines and its pilots’ union reached a preliminary labor agreement on Monday, ending three-and-a-half years of tense negotiations. 

The five-year contract is worth $12 billion and is one of the largest contracts, giving pilots significant raises, according to CNBC. United Airlines’ contract with its pilots union was worth $10 billion; Delta Air Lines was $7 billion; and American Airlines was $9.6 billion.
